What is PT-141?

PT-141, or bremelanotide, is a melanocortin agonist used to treat sexual dysfunction. It works by activating the brain's melanocortin receptors, which are thought to boost sexual arousal, desire, and erectile function.

Best Uses for PT-141

Increased libido
PT-141 increases physical arousal and genital circulation in both men and women, improving sensation and function. Two identical phase 3, randomized, double-blind, placebo-controlled, multicenter clinical trials evaluated the safety and efficacy of PT-141 in treating hypoactive sexual desire disorder in premenopausal women.
Better erectile function
In a double-blinded placebo-controlled study, approximately 80 percent of men developed an erection satisfactory for intercourse after using PT-141, and 68 percent of men reported an increase in sexual desire. In another study, PT-141 administration led to a dose-dependent increase in erectile activity.

I have been working with Invigor Medical for several months, and find their service to be excellent. Today I was contacted by Courtney, who was checking in to see how things were going. She was very nice and helped me to save money on my semaglutide injections by switching to a 2 month subscription. Thank you Courtney! You were so kind and helpful.

Frequently Asked Questions about PT-141

PT-141 stimulates melanocortin receptors in the brain in an area of the brain that affects sexual behavior. It increases libido in men and women and improves erectile function in men. PT-141 is also used to treat female sexual arousal disorder.

PT-141 is a prescription medication. If you are interested in PT-141, you will be asked to complete medical forms on the secure Invigor Medical platform. After completing these forms, you will meet with an Invigor Medical healthcare professional. If you have no contraindications to using PT-141, they will prescribe it and arrange for it to be delivered from one of our partner pharmacies.

PT-141 was developed from the Melanotan II peptide. When researchers explored the use of this peptide as a tanning agent, they noted an unusual side effect — increased libido and spontaneous erections. While it still promotes skin tanning, PT-141 is prescribed for its other effects: improving libido in men and women, improving erectile function, and treating hypoactive sexual arousal disorder.

PT-141 is injected just under the skin in fatty tissue, typically the skin on the lower right side of the abdomen. PT-141 is injected at least 45 minutes before sexual activity.

PT-141 is also available as a nasal spray.


Female arousal disorder or female hypoactive sexual desire disorder describes a condition in which women have little or no interest in sex. Women with this condition do not respond psychologically or physically to sexual stimulation. It is only considered a medical condition if the affected woman is distressed by the lack of arousal.

Based on DSM-5 criteria, sexual arousal disorder can be diagnosed when there is a decrease in three or more of the following:

  • Sexual or erotic fantasies or thoughts
  • Interest or arousal in response to erotic stimuli, whether internal or external
  • Interest in sexual activity
  • Pleasure or excitement during sexual activity (3/4 of the time)
  • Genital or nongenital sensations (3/4 of the time)
  • Initiating sexual activity or responding when a partner initiates sexual activity

Clinical trials have demonstrated the safety and effectiveness of combining PT-141 and sildenafil (Viagra). Investigators found that the combination (PT-141 and sildenafil) significantly increased erectile activity when compared to either drug used alone. Using PT-141 and sildenafil together did not cause any new side effects or increase the frequency of side effects when compared to using only one of the drugs.

Invigor's Commitment to Quality Medication

Our partner compounding pharmacies work with a registered and certified third-party lab to run quality control checks for every lot of compounded medications prescribed and delivered to our patients. These labs follow guidelines to ensure compounded medication safety and quality.
This test detects endotoxins (remnants of bacterial cell walls that can cause serious health problems) in pharmaceutical products. It helps ensure that medications are not contaminated by bacteria. Endotoxin limits are set based on how the medication is administered.
pH Test
This test measures the percent hydrogen (pH) or acidity or alkalinity of a product. The pH can affect the medication’s stability, solubility, and potency. To ensure the validity of the endotoxin test, the pH must be kept in a specified range.
Sterility Test
This test confirms that all sterile compounded medications are free from microbial contamination, including bacteria and fungi. Sterility testing reduces the risk of infections from taking medications.
Potency Test
This test measures the strength or the concentration of an active pharmaceutical ingredient (API) over time. It can be used in conjunction with stability testing to ensure that the medication will retain its potency until its beyond-use date.
